TECHNICAL AREA

Electric boxes and hanging brackets and more particularly adjustable electric boxes with parallel rails for connection with reciprocal parallel grooves in a hanging bracket that is configured to connect to a support, for example, a wall stud.

SUMMARY

Current adjustable box and bracket combinations use metal, e.g., steel, brackets, which significantly increases the weight of the combination and, as a result, the cost to ship the combination. In addition to the reduced weight and reduced cost for shipping, the plastic bracket acts as an electrical insulator and does not rust. In embodiments of the disclosed subject matter the box includes top and bottom pairs of outwardly extending interlocking teeth, e.g., raised ribs that connect and interlock with top and bottom pairs of reciprocally-shaped grooves formed in inner surfaces of two arms of the bracket. In addition, two spaced apart ribs on a body portion of the bracket connect and interlock with reciprocally-shaped grooves formed in a side of the box. This interlocking provides for a tight fit with less “wobbling” than with a metal bracket when the depth is adjusted using the adjustment screw and does not cause any loss of the internal volume of the box. In addition, in one or more embodiments the adjustable box and bracket combination includes multiple gussets on arms of the bracket for strength and stability.

Each protrusion 112 c formed inside the electrical box 100 by the groove 112 extends from a solid front end portion 113 with a flat front face 113 a that is contiguous with the top wall front face 111 back toward the back wall and connects with an inside of the rounded top corner 115 between the back of the top wall 110 and the top of the back wall 140. A channel 114 is formed in and through each protrusion solid front end portion 113 and into the grooves 112 a, 112 b and the channel 114 is configured and adapted to receive and engage fasteners from plugs, switches and the like. Each of the substantially parallel grooves 112 taper from a narrower front end 112 a to a wider open back end 112 b at the rounded top corner 115. A pair of raised ribs or rails 116 are formed on the top wall 110 between the first edge of the top wall 110 and the groove 112 on that side of the top wall 110. The front ends of the pair of raised ribs or rails 116 start at about the front end 112 a of the groove 112 and extend backward toward and end before the back edge of the top wall, although not clearly seen in FIG. 1 due to the position of the bracket 200. Additional details on the pair of raised ribs or rails 116 is provided herein below beginning with the description of FIG. 9 .

In FIGS. 1 and 5 , although only visible from their back sides on the bottom wall 150 a bottom pair of substantially parallel grooves 152 are formed in the bottom wall 150 and protrude into the inside of the electrical box 100 and the grooves 152 extend from a front end 152 a that is adjacent the bottom wall flat front edge 151 to a back end 152 b that opens out through the curved corner edge between the bottom wall 150 and the back wall 140. Each protrusion 152 c formed inside the electrical box 100 by the groove 152 extends from a solid front end portion 153 with a flat front face 153 a that is contiguous with the bottom wall front face 151 back toward the back wall and connects with an inside of the rounded bottom corner 125 between the back of the bottom wall 150 and the bottom of the back wall 140. A channel 154 is formed in and through each protrusion solid front end portion 153 and into the grooves 152 a, 152 b and the channel 154 is configured and adapted to receive and engage fasteners from plugs, switches and the like. Each of the substantially parallel grooves 152 taper from a narrower front end 152 a to a wider open back end 152 b at the rounded bottom corner 155. A pair of raised ribs or rails 156 are formed on the bottom wall 150 between the first edge of the bottom wall 150 and the groove 152 on that side of the bottom wall 150. The front ends of the pair of raised ribs or rails 156 start at about the front end 152 a of the groove 152 and extend backward toward and end before the back edge of the bottom wall 150, although not clearly seen in FIG. 1 due to the position of the bracket 200. Additional details on the pair of raised ribs or rails 156 is provided herein below beginning with the description of FIG. 9 .

In FIGS. 1 and 3 , multiple, evenly spaced, shallow grooves or depth marks 119 are formed in the top wall 110 adjacent a front end of and substantially perpendicular to the pair of raised ribs or rails 116. These depth marks line up with the front face of the flange portion 240 of the bracket 200 to indicate adjustment depth. Each depth mark 119 extends from an inside one of the pair of raised ribs or rails 116 and extends to and around the edge between the top wall 110 and the first sidewall 120 and extends down the entire length of the first sidewall 120 to and around the edge between the first sidewall 120 and the bottom wall 150 adjacent to a front end of and substantially perpendicular to a bottom pair of raised ribs or rails formed on the bottom wall 150 (best shown in FIG. 13 ). In the embodiment in FIG. 1 , the depth marks 119 are spaced at about ⅛ inches apart and permit adjustment of the electrical box from about ⅛ inches up to about 1% inches. The pair of raised ribs or rails on the bottom wall are formed as mirror images of the pair of raised ribs or rails 116 on the top wall.

In FIGS. 1, 2 and 3 , an opposite pair of raised ribs 117, 157 extend from an inside surface 118 (best seen in FIG. 2 ) of the top wall 110 and an inside surface 158 of the bottom wall 157, respectively, and are configured and adapted to cooperatively receive and hold an optional, removable divider wall (not shown). Four top knockout openings 161 are formed in the rounded top corner 115, although only three are visible in FIG. 1 , because the fourth is obscured by the bracket 200. Four removable top knockout tabs 160 (best seen in FIG. 2 ) are formed in the top knockout openings 161. Similarly, four bottom knockouts 165 and bottom knockout openings 166 are formed across the rounded bottom corner 125, although only three are visible in FIG. 1 , because the fourth is obscured by the second sidewall 130.

In FIG. 1 , in the first sidewall 120 the inside surfaces of a pair of substantially parallel grooves 122 are shown formed in the first sidewall 120 and extend backward from just adjacent the flat front edge 121 of the first sidewall 120 to and through the corner connection between the back wall 140 and the first sidewall 120. In between the pair of substantially parallel grooves 122 a central groove 124 is also formed in the first sidewall 120 and extends backward from the flat front edge 121 of the first sidewall 120 to and through the corner connection between the back wall 140 and the first sidewall 120. The central groove is configured and adapted to receive an adjustment screw 170 with the head of the screw 170 being shown positioned in the central groove 124 and adjacent the flat front edge 121 of the first sidewall 120.

In FIG. 1 , the bracket 200 includes a top arm 210 connected at a substantially perpendicular angle to a body 230 that extends toward and connects to a bottom arm 220 at a substantially perpendicular angle to the body 230 so that the top arm 210 and the bottom arm 220 are substantially parallel to each other and the bracket has a substantially “U”-shape. The top arm 210 includes a plurality of gussets 211 that extend and taper down from the top arm 210 and body 230 connections to a front end of top arm 210. In some of the various embodiments, the gussets 211 can have a thickness of, for example, but not limited to, between about 70/1000 to about 86/1000 inches. A top positioning portion 213 is located in a center of the first arm 210 and between pairs of the gussets 211. A plurality of cross gussets 212 connect at substantially perpendicular angles to and between the gussets 211 and the top positioning portion 213 to provide additional stability and support. A large flange head fastener 219, for example, but not limited to, a pan head screw, is positioned through the positioning portion 213 and into the support member 20 to hold the assembly 10 in position and reduce stress on the positioning portion 213. Although not seen, a second large flange head fastener 219 is positioned through a substantially identical positioning portion on the lower arm 220 and into the support member 20 to hold the assembly 10 in position at the bottom. The flange side openings of a pair of grooves 217 are formed in and extend across the width of an inside surface of the top arm 210 to and out substantially identical back side openings of the pair of grooves 217 (not shown) and are configured and adapted to slidingly engage the pair of raised ribs or rails 116 on the top wall 110.

In FIG. 1 , the bracket 200 includes a flange portion 240 on the side of the bracket adjacent to the front opening 160 of the electrical box and extending substantially perpendicularly away from a back side of the body portion 230 of the bracket, which forms a substantially right angle inside corner to be positioned against a substantially right angle outside corner of the support member 20. The flange 240 has a minimal thickness and a slightly inwardly tapering outer edge 245 and includes multiple fastener openings 241 formed through it to permit the bracket 200, either with or without the electrical box 100 being attached to it, to be initially positioned against the support member 20 using one or more fasteners. The tapering outer edge 245 helps form a more even or smooth positioning of the wallboard when it is placed over the flange 240. For example, but not limited to, in the embodiment in FIG. 1 , the flange 240 can have a thickness of about 78/1000 inches. The fastener openings 241 are counter-sunk to enable a fastener head to recess to about the same level as a front of the flange to minimize the thickness offset behind the wallboard, for example, but not limited to, drywall.

FIG. 2 is a front view of the electrical box and bracket apparatus shown attached to a support member of FIG. 1 , in accordance with an embodiment of the disclosed subject matter. In FIG. 2 , the four top knockout tabs 160 and the top knockout openings 161 and the four bottom knockout tabs 165 and the bottom knockout openings 166 are shown and include substantially rounded corners with approximately 0.15 inch radii. Ends of the bottom raised ribs or rails 156 on the bottom wall 150 are seen positioned inside a bottom pair of grooves 227 formed in and extending across the width of an inside surface of the bottom arm 220 to and out substantially identical back side openings of the pair of grooves 227 (not shown) and are configured and adapted to slidingly engage the bottom pair of raised ribs or rails 156.

FIG. 3 is a left, top front perspective view of the electrical box and bracket apparatus shown attached to a support member of FIG. 1 , in accordance with an embodiment of the disclosed subject matter. In FIG. 3 , the positioning portion 213 has a substantially cylindrical body extending at a slight downward angle from about the middle of the top arm 210 to and connecting to the back side the wall of the bracket body 230. This is best seen and described below in and in relation to FIGS. 9 and 10 .

FIG. 4 is a top, left rear perspective view of the electrical box and bracket apparatus shown attached to a support member of FIG. 1 , in accordance with an embodiment of the disclosed subject matter. In FIG. 4 , the back side of the back wall 150 includes the open back end of central groove 124 formed in the corner between the back wall 140 and the first side wall 120. In addition, the back sided of the top knockout tabs 161 and the bottom knockout tabs 165 are shown formed in the rounded corner 115 between the top wall 110 and the back wall 140 and the rounded corner 125 between the back wall 140 and the bottom wall 150. A partial view of the bottom arm 220 of the bracket, including a bottom positioning portion 223, a second large flange head fastener 229, for example, but not limited to, a pan head screw, and the back side openings of the pair of grooves 227.

FIG. 5 is a top, rear left perspective view of the electrical box and bracket apparatus shown attached to a support member of FIG. 1 , in accordance with an embodiment of the disclosed subject matter. In FIG. 5 , the bottom knockout tabs 165 and the bottom knockout openings 166 are more clearly shown formed in the rounded corner 125 between the back wall 140 and the bottom wall 150. In addition, a clearer view of the back side openings of the pair of grooves 227 in the bottom arm 220 are shown.

FIG. 6 is a left side view of the electrical box and bracket apparatus shown attached to a support member of FIG. 1 , in accordance with an embodiment of the disclosed subject matter. In FIG. 6 , front views of the top arm 210 and the bottom arm 220 of the bracket 200, which is fastened to the support member 20 by fasteners 219 and 229, are shown positioned above and below the electrical box 100. Both the top wall 110 and the bottom wall 150 can, but do not need to in all embodiments, extend from the back wall 140 at interior angles equal to or greater than 90 degrees. For example, in some embodiments, the top wall 110 can extend upwardly and away from the back wall 140 at an angle of up to about 2 to 3 degrees above 90 degrees and the bottom wall 150 can extend downwardly and away from the back wall 140 at an angle of up to about 2 to 3 degrees above 90 degrees. As a result, sidewalls 110, 130 can be larger at the flat front faces 111, 131 than at their respective back edges adjacent the back wall 140. In addition, due to the size of the positioning portion 213, the length of the cross gussets 212 between the two interior gussets 211 and the positioning portion 213 are shorter than the length of the cross gussets 212 between the two interior gussets 211 and the two outer gussets 211. The same is true for the bottom arm 220; due to the size of the positioning portion 223, the length of two cross gussets 222 between two interior gussets 221 and the positioning portion 223 are shorter than the length of two cross gussets 222 between the two interior gussets 221 and two outer gussets 221.

Alternatively, in other embodiments of the electric box 100 in FIG. 1 , as well as the other embodiments of the electric box(es) shown and described herein, the top wall 110 can extend away from the back wall 140 at an angle of 90 degrees and the bottom wall 150 can extend away from the back wall 140 at an angle of 90 degrees. As a result, sidewalls 110, 130 are substantially the same size at the flat front faces 111, 131 as at their respective back edges adjacent the back wall 140. In addition, the length of the cross gussets 212 between the two interior gussets 211 and the positioning portion 213 are substantially equal to the length of the cross gussets 212 between the two interior gussets 211 and the two outer gussets 211. The same is true for the bottom arm 220; the length of two cross gussets 222 between two interior gussets 221 and the positioning portion 223 are substantially equal to the length of two cross gussets 222 between the two interior gussets 221 and two outer gussets 221.

These differences in height relative to the box allow the tips of 116 and 156 to be substantially horizontal in those embodiments in which the top wall 110 and the bottom wall 150 extend away from the back wall 140 at angles greater than 90 degrees. In addition, a distance FF between the top front end 116 f and the bottom front end 156 f and a distance RR between the top rear end 116 r and the bottom rear end 156 r are substantially equal. However, in other embodiments where the top wall 110 and the bottom wall 150 extend away from the back wall 140 at angles of 90 degrees, the height TF is equal to the height TR.
